Because he still has at least 1 year on his contract. Sometimes it is stipulated that you won't get paid if you accept another coaching job before your contract is over. Or that they will pay the difference between the contracts if you are getting paid less than he was at Buffalo.

So, if he wouldn't get paid if he gets another job then I don't imagine he would take a job with a coach on the hotseat when he can get paid head coach money to sit on the beach or work in a booth commentating.

Again, if Buffalo only paid the difference, he could not work and get paid the same amount as he would to be the coordinator so he may want to take a year off and just get paid and not do anything.

If there are no stipulations like that, he might jump at a chance to add to his income and get paid by the Panthers and Buffalo.
